What is the greatest sin you've done in your life?

Neither of those are sin, Christians just don't understand what sin is, the word itself means "to miss the mark" how is being gay missing the mark? It's not, it only used to be because being gay basically sentenced your entire family to starvation, last I checked your kin aren't starving to death because you have a partner are they? Also Jesus would prefer you be an athiest than a false Christian. Everyone is saved anyway so even 'belief' isn't necessary to be resurrected in the kingdom on earth.
